WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 716,425, dated December 23, 1902. Application filed August 26,1902. Serial No. 121,063. (No model.)

T (0 whont it may concern:

Be it known that I, JOHN IMEL, residing at Emerson No. 2, in the countyof Montgomery and State of Iowa, have invented certain usefnlImprovements in VVagon-Brakes; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the to same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and novel improvement in brakes.

The object of my invention is to provide a' brake more particularly adapted to be used in connection with wagons, but which may also he used in connection with other vehicles, such as cars;

In the accompanying drawings I have shown in Figure l a bottom view of an ordinary farm-wagon provided with my brake. Fig. 2 shows a sectional view of the brakebeam, disclosing one of the end brackets. Fig.

3 shows a top View of the end of the rockshaft and one of the connected sliding cams. Fig. at shows a front view of one of the intermediate brackets. Fig. 5 shows an enlarged side view disclosing the position of the cam and brake-shoe, while Fig. 6 shows a sectional view of one of the intermediate brackets as used in my invention.

The aim of my invention isto provide a brake-beam provided with'bracketsupported brake-shoes and so constructed that the same may be secured to any ordinary wagon, the

brackets, as well as the brake-shoes, being adjustably secured.

In constructing a wagon-brake embodying o myinvention I provide a brake-beam B of any suitable length, width, and thickness and adapted to be secured to the bottom or reach of an ordinary wagon-box. This brake-beam is provided with two terminal brackets a, one

5 of which is shown in side view in Fig. 2,

which are adapted tostride the brake-beam B, each being provided with a slot 6, these terminal brackets being used in sets of twos,

as is shown in Fig. 1, and held by the bolts 0.

5o Adjacent the terminalbrackets a are held the intermediate brackets b, which are also bifurcated, so that they readily slide over the brake-beam. These brackets are further provided with the slots 6 and the seatings c, the slot e being of the same size as the slot 6 within the adjacent bracket a.

Supported by means of the intermediate brackets 19 and being revolnbly held within the seating c is a rock-shaft O, which rockshaft, however, has square terminations, as is shown in Figs. 3 and 5, and slidably held upon these square ends 9 are the cams D, as disclosed. This shaft 0 has its square ends g projecting through the terminal brackets a, which are so positioned that a small opening cc is provided, as is shown in Fig. 2. In order to keep this rock-shaft C from becoming laterally displaced, I provide the same with the set-collars 9, as is shown in Fig. 1. These collars are provided with ordinary set-screws, so that they may be given proper adjustment upon the rock-shaft.

\Vorking within each set of brackets a and b is a shoe-keeper F, provided with the projecting trunnions H, which trunnions slide within the slots 6, as is disclosed in Figs. 1 and 5. These shoe-keepers are provided with the projecting ears is, adapted to be engaged by the cam D, and secured to these shoekeepers F are the brake-shoes E, which are adapted to work against the periphery of the rear wheels 8 of the wagon.

At a suitable point the rock-shaft O is provided with the arm a, to which is secured the reach-bar 6, secured to an ordinary brakelever 5, working in conjunction with a suitable notched sector, as is usual in farmwagon construction, so that the shaft C may be rocked to actuate the cams D to carry the shoe-keepers backward and forward within their respective brackets. In Fig. 5 the arm a is shown as tilted, so that the cam D forces the brake-shoe against the wheels, as illustrated.

Secured to the brake-beam B and adjacent 5 the cams D are the rub-ironsf, so that the rear edge of each cam D when the brakeshoe is on rides against its rub-iron.

Now should a wheel slightly spring or work outward, as occasionally happens in connection withold farm-wagons, the operator can carry the brackets a and b outward, so that the brake-shoe and cam will adjust themselves so that the brake-shoe will Work upon the Wheel.

WVhile the brake-beam B has been described as being secured to the wagon-box A, it is of course understood that the same could be secured to the reach of the Wagon or be suitably supported by means of hangers, as the conditions may require.

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-- The combination with a brake-beam, of a forked bracket near each end, each end bracket being provided with a longitudinal slot, an intermediate bracket positioned adjacent each end bracket, each intermediate bracket being provided with a longitudinal slot and a shaft-seating, all of said brackets being adapted to stride aforesaid brake-beam, aforesaid end brackets being positioned forward of aforesaid brake-beam, so as to provide a suitable shaft-opening, a rock-shaft having square terminations positioned within said shaft-openings, of a curved cam slidably held upon the square ends of said rock-shaft, one cam being positioned between each set of brackets, set-collars secured to said shaft to prevent lateral displacement, a shoekeeper provided with projecting trunnions, said trunnions working within the slots of said brackets, each shoe-keeper being provided with a projecting ear adapted to be engaged by one of said cams, brake-shoe secured to each shoe-keeper, and an arm se cured to aforesaid rock-shaft to operate the same, all arranged substantially as, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
